How ultracold, superdense atoms become invisible
An atom's electrons are arranged in energy shells. Like concertgoers in an arena, each electron occupies a single chair and cannot drop to a lower tier if all its chairs are occupied. This fundamental property of atomic physics is known as the Pauli.....»»
Experiment sets new record in search for dark matter
Figuring out the nature of dark matter, the invisible substance that makes up most of the mass in our universe, is one of the greatest puzzles in physics. New results from the world's most sensitive dark matter detector, LUX-ZEPLIN (LZ), have narrowe.....»»
Physicists ease path to entanglement for quantum sensing
Nothing in science can be achieved or understood without measurement. Today, thanks to advances in quantum sensing, scientists can measure things that were once impossible to even imagine: vibrations of atoms, properties of individual photons, fluctu.....»»
First visualization of valence electrons reveals fundamental nature of chemical bonding
The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan. As the interactions between atoms are governed by the valence.....»»
Earth"s oldest, tiniest creatures are poised to be climate change winners—and the repercussions could be huge
The world's oceans are home to microscopic organisms invisible to the human eye. The tiny creatures, known as "prokaryotes," comprise 30% of life in the world's oceans......»»
Research team uses tunable laser to develop straightforward broadband spectroscopy method with Hz-level precision
Since the first demonstration of the laser in the 1960s, laser spectroscopy has become an essential tool for studying the detailed structures and dynamics of atoms and molecules. Advances in laser technology have further enhanced its capabilities. Th.....»»
Invisible laser beam detects what a MacBook user is typing
A whitehat hacker has demonstrated the use of an invisible laser beam to detect what a MacBook user is typing, from a distance, through a window, without being able to see the keyboard … more….....»»
Ultrasmall Space Junk Can Be an Invisible Satellite Killer. Scientists Are Learning How to Track It
An ambitious U.S. government program is working to detect and track millions of tiny space junk pieces—down to the size of a sand grain—throughout low-Earth orbit and beyond.....»»
Apple Watch owner credits device for saving his life with low heart rate feature
continues to be an essential product for everyone with its lifesaving health monitoring features. The latest story comes out of California, via KTLA’s Rich DeMuro, and it specifically shows how one invisible feature can lead to discovering an invi.....»»
Born to modulate: Researchers reveal origins of climate-controlling particles
Aerosol particles are tiny. Swirling suspended in the air around us, most are smaller than the smallest bug, thinner than the thinnest hair on your head, gossamer specks practically invisible to the naked eye. Newly formed ones are nano-sized. Yet th.....»»
Scientists pin down the origins of the moon"s tenuous atmosphere
While the moon lacks any breathable air, it does host a barely-there atmosphere. Since the 1980s, astronomers have observed a very thin layer of atoms bouncing over the moon's surface. This delicate atmosphere—technically known as an "exosphere"—.....»»
Groundwater plays an invisible role supporting lakes
Nearly 90% of North America's lakes are located in Canada. That's why they make up such an enormous part of our landscape. Among their many vital functions, lakes are essential to the biodiversity of our territory and constitute indispensable oases f.....»»
First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission.....»»
Researchers discover graphene flakes in lunar soil sample
A study, published in National Science Review, reveals the existence of naturally formed few-layer graphene, a substance consisting of carbon atoms in a special, thin-layered structure......»»
New perspectives for using corals in climate research
Ancient ocean temperatures are most commonly reconstructed by analyzing the ratio of different oxygen atoms in the calcium carbonate remains of fossils. However, this presents many challenges, including a combination of biological processes known as.....»»
Investigation into the regime between the nano- and microscale could pave the way for nanoscale technologies
In electronic technologies, key material properties change in response to stimuli like voltage or current. Scientists aim to understand these changes in terms of the material's structure at the nanoscale (a few atoms) and microscale (the thickness of.....»»
Physicists use light to probe deeper into the "invisible" energy states of molecules
A new optical phenomenon has been demonstrated by an international team of scientists led by physicists at the University of Bath, with significant potential impact on pharmaceutical science, security, forensics, environmental science, art conservati.....»»
Breakthrough in Z-alkene synthesis: Scientists develop efficient and sustainable method
Z-alkenes are organic compounds with a double bond between two carbon atoms and two substituents attached to the carbon atoms on the same side of the double bond. They are ubiquitous structural components of organic compounds in chemistry and biology.....»»
Researchers trap atoms, force them to serve as photonic transistors
Researchers at Purdue University have trapped alkali atoms (cesium) on an integrated photonic circuit, which behaves like a transistor for photons (the smallest energy unit of light) similar to electronic transistors. These trapped atoms demonstrate.....»»
A camera trap for the invisible—a solution to difficult pattern recognition problem in experimental particle physics
It sounds fantastical, but it's a reality for the scientists who work at the world's largest particle collider......»»
Climate change will bring more turbulence to flights in the Northern Hemisphere, analysis finds
A type of invisible, unpredictable air turbulence is expected to occur more frequently in the Northern Hemisphere as the climate warms, according to new research. Known as clear air turbulence, the phenomenon also increased in the Northern Hemisphere.....»»
